Disclaimer: I already loved Fretwork vision of Bach’s The Art of Fugue. Several years ago I got this very cheap CD with the Harmonia Mundi catalogue: and felt in love with it. Nowadays is mostly agreed that Bach did The Art of Fugue as a intellectual exercise for composers/music students. It was intended as a study work not as a concert work. So the question “in which instrument(s) should it be played?
